Section5. FIRE-FIGHTING MEASURES
Suitable extinguishingDry chemical, foam, water spray, carbon dioxide.
media:
Unsuitable extinguishing Solid streams of water
media:
Specific hazards arising Take care as it may decompose upon combustion or in high temperatures to
from the chemical:generate poisonous fume.
Precautions for firefighters: Fire-extinguishing work is done from the windward and the suitable fire-extinguishing
method according to the surrounding situation is used. Uninvolved persons should
evacuate to a safe place. In case of fire in the surroundings: Remove movable
containers if safe to do so.
When extinguishing fire, be sure to wear personal protective equipment.
Special protective
equipment for firefighters:

---

Section6. ACCIDENTAL RELEASE MEASURES
Personal precautions,Use extra personal protective equipment (self-contained breathing apparatus). Keep
protective equipment and people away from and upwind of spill/leak. Ensure adequate ventilation. Entry to non-
emergency procedures: involved personnel should be controlled around the leakage area by roping off, etc.
Environmental precautions: Prevent product from entering drains.
Methods and materials for Absorb spilled material in a suitable absorbent (e.g. rag, dry sand, earth, saw-dust).
containment and cleaning In case of large amount of spillage, contain a spill by bunding. Adhered or collected
up: material should be promptly disposed of, in accordance with appropriate laws and
regulations.

Section7. HANDLING AND STORAGE
Precautions for safe handling
Technical measures:Handling is performed in a well ventilated place. Wear suitable protective equipment.
Prevent generation of vapour or mist. Wash hands and face thoroughly after
handling.
Use a closed system if possible. Use a ventilation, local exhaust if vapour or aerosol
will be generated.
Advice on safe handling:Avoid contact with skin, eyes and clothing.
Use corrosive resistant equipment.
